Click and drag in the image and look what happens!
Using a little bit of phantasy, you can produce amazing pieces of art.

Explore what happens if you repeatedly perform some particular warp operation of
your choice!
Furthermore, explore what happens if you repeatedly perform a sequence of two
operatons (e.g. crosswise - horizontal, vertical, horizontal, vertical,... -
or diagonal crosswise, i.e. following the shape of an x)!
Do you recognize the emergence of fractal
type structures?
(In simplified terms, a fractal
is a pattern repeating itself on smaller and smaller scales. Such patterns
are also called self similar).

Without knowing the precise rules according to which an image follows from the
preceding one, try to think about the mathematical processes at work here!
What might be responsible for the structure emerging after a regular sequence
of warp operations?
Can you imagine natural processes to generate fractal patterns in a similar
way?
